APPARATUS FOR MAKING FRUIT EXTRACTS.

the art to which it appertains to make and use the same, reference being had to the ac companying drawings, forming part of this specification.

My invention relates to an apparatus for making fruit extracts and the object of my invention is to provide an apparatus in which the condition of the material can be constantly inspected and in which the temperature of the material in the apparatus may be accurately regulated.

The accompanying drawing is a sectional view of one form of apparatus made in accordance with my invention.

1 represents a retort which may be of any suitable shape but is preferably approximately spherical as shown in the drawing. Contained within the retort 1 is a cylindrical strainer 2 provided with a flange 3 at its upper end. This flange 8 is clamped between the body of the retort 1 and the cover a of the retort. This cover at is held in position by means of swing bolts 5 pivoted at 6 to the body of the retort and connecting with lugs 7 on the cover 41. Leading from the cover 1 of the retort to a suitable condenser S is a pipe 9 by means of which the products of distillation are carried over from the retort to the condenser. In order to lift the strainer 2 out of the retort 1 the said strainer is provided with handles 10. In order to inspect the interior of the retort 1 I provide the walls of said retort at one side with a glazed side opening 11 and at another point in the wall, preferably diagrammatical opposite to the side opening 11 I insert in the walls a transparent tube 12 for receiving an incandescent light bulb or any other suitable source of light for illuminating the interior of the retort.

In order to take the temperature of the contents of the retort I insert in the walls of the retort-- a tube 13 adapted to receive a thermometer. This tube 13 should be of some good conducting material such, for instance, as copper.

14 is a pipe leading from the bottom of Specification of Letters Patent.

the retort 1, and 15 is a pipe leading from the retort near its upper end. These pipes 14 and 15 are connected by means of a glass tube 16 forming a water gage to indicate the height of the contents of the retort 1. The flow of liquid through the pipes 14, 15 and 16 is controlled by means of a valve 17 and the pipe 1% is provided at its outer end with a pet cock 18 by means of which the contents of the retort 1 may be drawn oif. In order to insert liquid in the retort 1 without removing the cover 4 I provide the walls of the said retort with a threaded plug 19.

In order to heat the retort 1 I provide around its lower part a water acket 20 adapted to beheated by means of a gas burner 21. This burner 21 is supported in a sleeve 22 the upper end of which is secured to the retort 1. The water jacket 20 has leading from it pipes 23 and 24 respectively, which are connected by means of a glass tube 25 forming a water gage for the contents of the water jacket. The pipe 2 1 is also preferably provided with a pressure gage 26 to indicate the pressure of the contents of the water jacket 20. The flow of liquid through the pipes 23, 24: and 25 is controlled by means of a valve 27 and the outer end of the pipe 23 is provided with a pet cook 28 for drawing off the contents of the water jacket 20. In order to introduce water into the jacket 20 I provide a container 29 connected to the said water jacket 20 by means of a pipe 30 in which is a valve 31.

In making fruit extract in my apparatus the crushed fruit together with sugar or other necessary material is placed within the perforated strainer 2 so that the fruit pulp is kept out of contact with the walls of the retort 1. Within the retort 1 is placed the necessary liquids for extracting the aroma from the fruit pulp. The retort 1 is heated by means of the burner 21 and as the water jacket 20 is interposed danger of overheating the contents of the retort 1 is obviated. By means of the side opening 11 and illuminating tube 12 the contents of the retort 1 may be continually observed so that the distillation may be carried on the proper length of time and at the proper rate.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In an apparatus for making fruit extoo tract, the combination with a retort, of a shell inclosing the lower part of said retort and forming a water jacket, a pipe leading from the lower part of said shell, a water gage extending from said pipe to the upper part ofsaid shell, a valved reservoir connected to the water jacket for supplying water thereto, a sleeve surrounding said water jacket and forming a support for the retort, said sleeve also forming a combustion chamber, and a burner situated within said combustion chamber.

2. In an apparatus for making fruit extract, the combination with a retort, of a shell inclosing the lower part of said retort and forming a water jacket, a sleeve sur rounding said Water jacket, a pipe leading from the lower part of said shell through said sleeve, a water gage connecting said pipe with the upper part of said shell, a second pipe leading from the lower part of said retort through said shell and said sleeve, a second water gage connecting said pipe with the other part of said retort, and a valved reservoir connected with said jacket for supplying water thereto.

3. In an apparatus for making fruit ex tract, the combination with a retort having Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

a restricted mouth, of a substantially cylindrical foraminous container provided with a flange adapted to rest on the lip of said mouth, a cover and means for clamping said cover against said flange, a pipe leading from said cover, and a condenser connected to said pipe.

4;. In an apparatus for making fruit eX- tract, the combination with a retort having a restricted mouth, of a substantially cylindrical foraminous container provided with a flange adapted to rest on the lip of said mouth, a cover provided with lugs, swing bolts pivoted to said retort, nuts on said swing bolts adapted to engage With the lugs to clamp said cover against said flange, a pipe leading from said cover, a condenser connected to said pipe, a shell inclosing the lower part of said retort and forming the water jacket, a sleeve surrounding said jacket, and a burner in said sleeve. In testimony whereof, I have hereunto set my hand and afiiXed my seal in the presence of the two subscribingwitnesses.
